Tracked a bootstrap failure with SMS flags on ARM machine exposed in recent trunk. Fixed and tested a patch for that. Tested another SMS patch following comments received from gcc ml@ (http://gcc.gnu.org/ml/gcc-patches/2011-05/msg02294.html)

Following conversation with Micheal, added SPEC2006 analysis info to the benchmarks wiki page -https://wiki.linaro.org/Internal/ToolChain/Benchmarks

Discussed with Ramana weird RTL pattern generated for thumb2_movhi_insn with -march=armv7-a -mthumb using trunk. Probably will open a PR for that.
